YETI Rambler MagSlider Lid

Q: Does this fit on an rtic 30oz tumbler?

It won’t definitely fit your new design Rtic tumbler, new vs old design? New it’s just the bear with R embeded within, the old design spells rtic around the base. The new design it’s 3-7/8” wide at the mouth while the Yeti and rtic old designs are 3-3/4”, believe me, I’ve done some research and ordered for the 4th time and I’m still getting the small lids that won’t fit my rtic new design such a pain, even with the descriptions reading that’ll fit my new design, ugh! Contemplating to buy a new cup now.

Q: Does this fit on yeti rambler 14oz mug ?

The 30 oz magslider fits on the 14oz mug

Q: Have anyone had an issue with the slider not working like the video someone posted?

The one in video doesn’t look like the YETI one.
